HTTP Request Cache

Provides a wrapper around drupal_http_request() that will, by default, cache outgoing GET requests. Also defines an alter hook so that other modules can adjust if a request is cached or not.

Requirements

No additional requirements.

Usage

Just enable the module and it will start caching outgoing GET requests. More complex rules require implementing an alter hook.

hook usage

/**
 * Implements hook_http_request_is_cacheable_alter().
 */
function MYMODULE_http_request_is_cacheable_alter(&$is_cacheable, $context) {
 
  // Try and limit to only Solr requests to minimize possible issues.
  $is_cacheable &= strpos($context['url'], '/solr/') !== FALSE;
}
